great deal for the cost
I am not a full time machinist. The collets work great for what I need them for. The price was good and I am sure that they will last me a long time since most of their life will be spent in a drawer.

Very consistent with an average run-out of .0002" on the 8 out of 12 holders I have dial tested
Got these as a brand new set that came with my PM-45M CNC. The person I purchased the machine from also included a set of 20+ Tormach ER20 tool holders & Tormach R8 to Tormach tooling adapter(just an R8 collet). When comparing the the run-out using the Grizzly R8 collets vs the Tormach Tool holders on a .0001" gradient dial test indicator I am seeing an average of .0002" and a max of .0004" run-out at the end mills shank using the Grizzly collets. With the Tormach holders no matter what I do simply loosening them and re-tightening the holders can cause up to .0018" of run-out to occur when the previous mounting seconds before showed less than .0007". I have tried using the grizzly R8 collet with the Tormach holders, clocking the ER20 collets and even going to high end collets/end mills but always the Tormach tooling system just does not like to mount consistently in the R8 tooling. Maybe this would change with a powered drawbar vs a bolt/nut style but either way I'm surprised the Tormachs come as highly recommended as they do and the Grizzly's are considered poor quality by comparison. IMO .0002" average run-out is amazing for the price and I am now considering selling the Tormach holders or going to a BT30 spindle & powered drawbar. NOTE: The attached photo shows less than .0001" run-out at the end mill. I have zero set @ #2 for clear indication of negative and positive.
